MikeP:
Thanks for the prompt reply, I appreciate that the ERP is much lower on the Local M Multiplex. (and looking at the target area Winter Hill isn't really the best place for it! )
I don't have a signal strength meter but if it's any help as a comparator I can receive the main multiplexes with a long piece of wet string, or a pair of rabbit ears!
M45 area, am I able to message my postcode directly to you?
regards

We need you to put your full post code into this website as then we get to see the series of small blue boxes (links) beneath your postings. Only then can we see what the reception conditions are at your location.

You normally don't need a signal strength meter as most Freeview televisions provide a strength and quality reading. Check your User Manual for how to display that on the TV screen.

You should not assume that just because the 'normal' channels are strong then the local chanel will be as well, they usually use a direction aerial system to control the coverage area and prevent interference with other transmissions.

Mike, thanks for the reply.
My comments about the signal strength were from having looked at various TV's Signal strength/quality indicators.
Other multiplexes are showing 95 to 100% with no errors on the SD channels and some (concealed) errors on the HD Multiplexes.
The LM Multiplex is showing approx. 18% with no errors. Pity I never looked at the Local strength before the recent retune.
I think I'd be more likely to cause interference issues on the good channels if I were to boost the signal.
I'd be interested to hear what sort of strength others are seeing when comparing the main multiplexes with the Local M, when their locations are similar, although It's unlikely anyone else would be interested as the audience share is tiny.
Sorry about the postcode thing, I finally figured out how to enter it!
Thanks for all your help.

Just a curiosity - how do Winter Hill transmitter engineers measure the field strength coverage? Is it all theoretical or do they go to pre-defined locations and actually measure it?
Thanks

Woz:

Look at the predicted signal reception at Coverage Checker - Detailed View This shows you should get signals on the L-Man multiplex (channel 56) reasonably well but unlikely to get reliable reception on the G-Man multiplex (channel 57).

If your signal strengths are above 85% for any channel, especially HD ones, then you have too much signal and that can cause serious break up of sound and/or picture. So fitting an amplifier would be counterproductive as it would destroy what is currently reasonable reception! In fact, you should reduce the received strngths slightly with a 3 dB attenuator, that should give better results, especially on the HD channels. You do not want the strength to be less than 60% for HD or 50% for SD.

I suspect that you will not be able to enjoy the G-Man services and may not have reliable L-Man services.



Transmission of the L-Man and G-Man multiplexes is directional and now all round the transmitter, so it seems you are outside the predicted reception area for G-Man and perhaps on the edge for L-Man.

Signal radiation patterns are determined both by local measurements and computerised predictions based on those measurements and knowledge of the terrain. The operators do recheck from time to time by doing field measurements, especially if a new aerial is fitted to the mast. For example, a local multiplex is usually intended to have a limited coverage area and to avoid interference with other signals they check that the aerial it uses is aimed correctly to give the desired coverage.

Hi, I recently got a new TV (old one didn't have freeview hd) and now have HD but have noticed some HD channels are saying no signal. They all seem to be com 7 (and maybe com8) and show on the EPG. The aerial is high on the roof and seems to have two rods however all the neighbours have a single rod. The gent I bought the house from was 88 so it may not have been updated for sometime. Do you think the aerial may be the issue or that I am not in the right area (wn68ds) for com 7?
Cheers, Andy.

Anday:

Having looked at the blue links below your posting, namely the 'digitaluk trade' (at Coverage Checker - Detailed View and the 'Freeview map' (at Freeview reception at WN68 DS) it should be perfect reception. However, is your aerial a Group C/D type or a wide band type? Com7 is on channel 31 and most Group C/D aerials are poor at that lower frequency, so will need to be replaced by a wide band type, preferably a log-periodic which will be suitable for several years. Com8 is on Channel 37 which should be being picked up by your aerial, though it may be weaker than you 'main' channels.

So you need to do a signal strength check on channels 31, 37 and 49 (the ArqA multiplex). For good HD reception you need signal strength between 60% and 85%, any less is too weak and any more is too strong for reliable reception of HD services.

One other possible source of problems are the 4 mobile masts quite close to your location. If they are a source of problems you shoudl contact At800 (see https://at800.tv/contact-us/) and discuss any issues with them.

Andy: Give us a model and make of the TV to make sure it does have an HD tuner. But if you are getting 101, etc, but not other HD channels, then your either in an area which doesn't have those services (light transmitter?), or you have a problem with your system.

Check signal strength and then the signal path - if the TV is telling you there is no signal, the TV is OK and telling you its your system. Could be as basic as a rubbish aerial lead into the TV.

Hi Mike & Mike,
sorry for the delayed reply but didnt get a notification of your comments so just found it when re looking.

I think the tv should be fine as like you say I am getting other hd channels but its a panasonic TX-50CX700B. I'm not sure what aerial it is but I don't think its wide band.

Just done a signal check and 31 is 0 signal quality and flashes on and off between 0- 52% signal strength. 37 has 100% signal quality and 30% signal strength and 49 has 100% signal quality and 94% signal strength.

Thanks.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
